Penny Aston is the most successful female racing driver in history. She's spent a decade fighting her way to the top of a male dominated arena, sacrificing everything she had and more besides at the altar of victory. Superstardom beckons. But at two hundred miles an hour, a split second is a lifetime - and in the blink of an eye she's spiralling towards oblivion, everything she worked for taken from her. She must risk her life, and the lives of those she loves, to regain what was hers - and lay bare a devastating secret which has lain hidden in plain sight for three decades. From the twists and turns of the world's greatest circuits, to the danger behind the glitz of the French Riviera, to its shattering climax among the pitiless mountains of the Scottish Highlands, Second Split is the story of one woman's fight for survival against impossible odds.
